USB 3.0 transferring slow (Lenovo Y480)

hey guys I just bought a 3TB USB 3.0 HDD. I'm backing up my old 500gb (also USB 3.0) hard drive onto it. They're both plugged into 3.0 ports, and I'm getting ~22MB/s. Is there any way to get real 3.0 speeds?

500gb drive - WD passport
3TB - Seagate Expansion desktop drive

EDIT: It's at 13.3MB/s right nowEdited by Ken.Turner - 7/9/13 at 8:30am

Are you transfering bunch of photos or stuff like that? Speeds can be lower if that is the case.

Also in my motherboard I had a feature called USB boost where the USB transfer speed was even faster. However it made the USB 3.0 speeed even slower for me. Almost 5 mb/s... So see if you have any feature like that for your laptop and disable it.
